Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599528, here are decompositions:

29 + 31599499 = 31599528
41 + 31599487 = 31599528
89 + 31599439 = 31599528
97 + 31599431 = 31599528
139 + 31599389 = 31599528
179 + 31599349 = 31599528
269 + 31599259 = 31599528
281 + 31599247 = 31599528

Showing the first eight; more decompositions exist.
